Supercharger type?, Which one?

Talking 85% street, the rest blown. I have finally decided to build a blown car, I understand ROOTS style offers instant torque and a lot of it, this fits my "street racing addiction", I also understand that a Vortech offers overall more power because of it's design. I guess my question is which ROOTS style would you go with on a 93 5.0, I am with it as far as fuel and tuning. I have done several nitrous cars, tired of filling that bottle, when you have nitrous, the only thing close is another Mustang!
